Hi.
I know that Jquery is not loading . I added script <script src=’https://www.printserviss.lv/wp-includes/js/jquery/jquery.min.js?ver=3.6.0′ id=’jquery-core-js’></script> to the header.php. I checked this script (https://www.printserviss.lv/wp-includes/js/jquery/jquery.min.js?ver=3.6.0). It work correct. But when I launch site separatly this script does not appears. How I can repare this error.
